Latest Patents
Ennis's latest patents include the "Power-line trip circuit" and the "Circuit interrupter arrangement." The power-line trip circuit is designed to model the transient characteristics of load changes, such as fault currents or normal load switch-ons. This innovative circuit compares the actual current flowing in power lines with a simulated transient model. It ensures that only fault currents, which exceed normal limits, will trip the associated circuit breaker, allowing for fast and reliable tripping even in the presence of substantial transient overshoot.
The circuit interrupter arrangement features a vacuum recloser that incorporates an isolator switch in series with the vacuum interrupter, driven by the same actuator. This design ensures that the isolator can only be operated when the vacuum switch is open and no arc current remains. This is achieved through a significant lost motion in the isolator drive or by latching the isolator drive against opening, which enhances safety and reliability in electrical systems.
